MOLD FOR SAS'H-WEIGHT CORES.

Application led September 29, 1925. Serial No. 59,251.

To all whom t may conce/m:

Be it known that I, JOHN J. FLEMING, a citizen of the United States, residing at Vineland, in the county of Vineland and 5 State of New Jersey, have invented certain new and useful Improvements in Molds for Sash-IVeight Cores, of which the following is a specification.

My invention relates to molds for sash l weight cores which are used in molding the cord-attaching end of sash weights.

The chief objection, common to the numerous methods` of making sash weight cores, is that considerable time is required for making the cores. costly item in the manufacture of sash weights. Another objection'is that the apparatus, used for making the cores on a large scale, is bulky and of many parts which makes it complicated and unhandy to use. A further objection common to many methods is that the weight indicating numbers are not molded on a conspicuous part of the sash weight which makes it diiicult to find a proper weight among a group of different weights.

The objects of my invention are to provide a mold for making sash weight cores, of comparatively simple and compact construction, which may be easily handled to quickly produce large quantities of cores at low cost; and to provide a mold which will produce a core of such character, that it will form a cord-attaching end on a sash weight having the weight indicating numbers in a conspicuous place.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which- Figure l is a plan view of a mold made in accordance with my invention,

Figure 2 a central section through the r mold shown in Fi ure 1 showing it lilled with sand, some o the parts being shown in full,

Figure 3 a view similar to Figure 2 showing some ol? the parts in another position,

Figure 4 a section on line 4 4 of Figure l,

Figure a section on line 5-5 of Figure 1 showing some of the parts broken away,

This makes them ak casing. Bar passages 5 are provided through the Walls of the cavities for slidably receiving a marking bar 6 and a plain bar 7 which pass through the cylindrical parts of the mold cavities. Marking bar 6 is provided with symbols 8, corresponding to the weight of the sash weight to be molded by the core, which are disposed in each cavity. Plain bar 7 passes through the cavities alongside of the marking bar to keep the same in position. A suitable locking member 9 in the form of a pin passes through the casing and through the bars to lock them to the casing. For purpose of simplifying the machining of bar passages 5, casing 1 is preferably made in lengthwise half sections so that half of each passage may be readily machined in one section and the other half in the other section.

In Figure 7, I have shown a form in which two marking bars 6a pass through the cavities QfL and passages 5a with their symbols 8a disposed in the cavities so that the cores produced will have two symbolimpressions thereon for molding two weight-markings on the attaching end of a sash weight. When this form is used the plain bar 7iL is placed between the marking bars and locked with them to the casing by the pin 9a. In all other respects the mold is similar to the mold shown in Figures l to 6 and I have therefore given corresponding parts similar reference characters with the exponent a In making the cores with my improved mold, the bar 6 and plain bar 7 are slid into the casing to pass through the cavities and locked thereto by the pin 9. The mold cavities are then lled and rammed with sand, after which pin 9 is removed and plain bar 7 slid out of the casing. Marking bar 6 is then shifted sidewise away trom the symbol impressions l() left in the sand and slid outot the easing. lVlien the form shown in Figure 7 is used, the other marking bar Ga is likewise shifted sidewise away from the impressions and slid out of the casing. The casing is then turned up`-side down and tapped slightly until the cores fall out or' the cavities. The core produced by each cavity is as shoivn in Figure 8. These cores are then used tor plugging the end ot a saslrneight mold and form the cord-attachingend on a sashlvxeight. The opening 'll in the core, having the symbol impressions l0 in its sides, iras formed by marking bar 6 and plain bar 7. This opening forms the fiat part on the end Ot the sash Weight. The part l2 of the core, which as formed b v the slotted part Ll olt the mold cavity, iorms the cord-attach ing opening through the liat part on the end of the sash weight. The symbol impressions l0, which are pr i rably numbers, form the number on the 1 .e walls ot' the flat part which may be easily seen at a glance.

It is thus seen that constructing a core mold as above set forth, produces a comparatively simple mold which may be conveniently handled to quickly produce large quantities of sash nfeight cores, and that the cores produced form a cord-attaching end on a sash weight vfhich has the Weight indicating numbers in a conspicuous place.

While I have described my invention as taking a particular form, it will be understood that the various parts may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope ol the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent isz l. A mold for making sash Weight cores including a casinghaving a mold cavity; a bar slidably mounted in the casing passing through the cavity and having a marking thereon disposed in the cavity, and a second bar slidably mounted in the casing adjacent the first mentioned bar.

2. A mold for making sash weight cores including a casing having a plurality of mold cavities; a bar slidably mounted in the casing and passing through the cavities and having a marking thereon disposed in each cavity, and a second bar slidahly mounted in the casing adjacent the marking bar.

3. A mold tor making sash weight cores includingl a casing having a mold cavity; a bar slidably mounted in the casing, passing through the cavity, and having a niarking thereon disposed in the Aavity: a .second bar slidahly mounted adjacent the irst mentioned bar and means 'tor locking the bars to the casing.

l. A mold for makingl sash weight cores including a casing having a` cyliniilrical part opening at one side and a .slotted part, communieating with the interior oi' the ovlindrical part, opening at the other sido; a bar slidably mounted in the casing passing through and having a n'iarki v used in the cylindrical part, and a second har slidably mounted in the casing adjacent thc first mentioned bar.

A mold including a sectional casing having a plurality ot mold cavities and aligned bar passages through the walls ol the cavities; a marking` bar sldably mount ed in the passages and having a symbol dii-iposed in each cavity; a second bar slidably mounted in the passages tor holding the marking bar in position, and means for locking the barsto the casing.

6. A mold including a sectional. casing having a plurality of mold cavities and aligned bar passages through the nails it the cavities; a marking ha r slidahli` mount' ed in the passages and having a syniboi d5.sposed in each cavity; a second bar slidably mounted in the passages :for holding thc marking bar in position, and a pin passing through the casing and thc lnirstor locking them to the casing.

In testimony whereof I have signed in i' name to this specification.

JOHN J. IPLEMING.
